“Hugh Laurie: Let Them Talk – A Celebration of New Orleans Blues” comes to PBS’ “Great Performances” at 8:30 p.m. on RMPBS, Friday, Sept. 30. The actor’s musical talents, which flicker through “House” occasionally, are on full display in this documentary/concert film, a love letter to New Orleans.

Blues legends Allen Toussaint and Irma Thomas show up for rehearsals and performances. A companion album has been released and Laurie hopes it won’t be his last. “This may be what heaven is like,” he says of jamming with the greats in the French Quarter.
